When it comes to food and drink, Martin says not to overload your plate with food. Get just enough to snack on and go back for more if you need it.

And you shouldn't drink more than two glasses of wine at your holiday office party. Each glass should only contain four ounces. "It can really sneak up on you. You think you've had two glasses when you've really had four," said Martin.

Lastly, avoid drinking beer out of a bottle because it's considered rude. Martin says the rule applies to both males and females.
